Hello,

I've ordered an oxygen sensor from Amazon after verifying the fit with the seller as well as with Amazon (website claimed that It would fit my car).

Car - 2005 Lexus es330

part - bank 1 sensor 2 (Denso)

I had a hell of a time getting the old one off. When it came time to put the new one on, the plug connector didn't fit. Was too wide. Do they make the plug connectors in only one size for each model of oxygen sensor?

Would appreciate your inputs on this matter.

use this link to source the Denso part # then cross reference with what you purchased via Amazon
Bank 1 Sensor 2 = down stream rear.
I recommend OE style

FYI - I have purchased Denso O2's from Amazon. One was sent with the Denso package in French Canadian, The O2 connector itself was correct but the wiring sequence was not correct (Canadian spec??). They then sent the proper O2.
